6 Claims, No Drawings ESTERS OF l-AMINOALKYL-CYCLOALKANOLS SUMMARY OF THE INVENTION The present invention relates to new l-aminoalkylcycloalkane compounds. Especially it concerns l-aminoalkylcycloalkane compounds of the formula alk-R,

wherein R denotes a cycloalkylidene residue with to 14 ring members, R denotes an acyl residue, alk denotes a lower alkylene residue which separates R, from R by 3 carbon atoms or a residue of the formula and R denotes a tertiary amino group, and their salts, and pharmaceutical preparations containing these compounds, as well as a process for treating bacterial and mycotic infections consisting in administering such pharmaceutical preparations to a warm-blooded being.

A cycloalkylidene residue R is for example a cyclodecylidene or cyclotetradecylidene residue, but especially a cycloalkylidene residue with 11 to 13 ring members, such as a cycloundecylidene or cyclotridecylidene residue, or above all a cycloalkylidene residue with 12 ring members, that is to say a cyclododecylidene residue. The cycloalkylidene residue can also be substituted, especially by lower alkyl residues, such as for example by those mentioned below, but above all by methyl or isopropyl residues. It is however preferably unsubstituted.

The residue alk can for example be a 1,3-propylene residue which can also be substituted by lower alkyl residues, above all methyl residues.

The tertiary amino group R, is especially an aliphatic tertiary amino group, that is to say an amino group which is disubstituted by one bivalent or two monovalent residues of aliphatic character. Here those residues are designated as residues of aliphatic character wherein the first member, linked to the nitrogen atom, is not a member of an aromatic system. Preferred residues of aliphatic character are aliphatic residues. As substituents of a tertiary amino group, the following may be mentioned by way of examples: lower hydrocarbon residues of aliphatic character, which may also be interrupted in the carbon chain by hetero-atoms, such as oxygen, sulphur or nitrogen atoms and/or substituted, for example by hydroxyl groups. Lower hydrocarbon residues of aliphatic character as substituents of the amino groups are above all alkyl, alkenyl, alkylene, alkinyl, cycloalkyl, cycloalkenyl, cycloalkyl-alkyl or cycloalkenyl-alkenyl residues or cycloalkenyl-alkyl or cycloalkenyl-alkenyl residues or aralkyl or aralkenyl residues, such as for example phenyl-lower alkyl or phenyllower alkenyl residues, which may also be substituted, for example as specified below for the aromatic rings, the above-mentioned residues possessing at most 8 carbon atoms. Residues of this nature which are interrupted by hetero-atoms are above all oxaalkyl or azaalkyl, oxaalkylene, azaalkylene, thiaalkylene or oxacycloalkylalkyl residues. Substituents of the amino groups which should be particularly mentioned are methyl,

2 ethyl, allyl, methallyl, propyl, isopropyl, propargyl, straight-chain or branched butyl, pentyl, hexyl or heptyl residues bonded in any desired position, 3-oxabutyl, 3-oxapentyl, 3-oxaheptyl, Z-hydroxyethyl, 3- hydroxypropyl, butylene-( 1,4), pentylene'-(1,5 hexylene-(1,5 hexylene-( 1,6), hexylene-(2,5), heptylene- (1,7), heptylene-(2,7), heptylene-(2,6), 3-oxapentylene-(1,5), 3-thiapentylene-( 1,5), 2,4-dimethyl-3-thi'apentylene-( 1,5), 3-azapentylene-(1,5), 3-lower alkyl-3-azapentylene-(1,5), such as 3-methyl-3-azapentylene-(1,5), 3-(hydroxy-lower alkyl)-3-azapentylene- (1,5), such as 3-(B-hydroxyethyl)-3-azapentylene- (1,5), 3-oxahexylene-( l ,6) or 3-azahexylene-( 1,6) residues, optionally lower-alkylated, such as methylated, cyclopropyl, cyclopentyl or cyclohexyl residues or cyclopropyl-, cyclopentylor cyclohexyl-methyl or -ethyl residues, or optionally substituted lor Z-phentylethyl, benzyl or cinnamyl residues.

The amino group R is thus for example a dilower alkylamino group, such as a dimethylamino, diethylamino, N-methyl-ethylamino, dipropylamino, diisopropylamino, dibutylamino, di-sec.butylamino or diamylamino group or a pyrrolidino or piperidino group which is optionally C-lower alkylated and/or B-singly unsaturated in the ring, or an optionally C-lower alkylated piperazino, N-lower alkylor N'-(hydroxy-lower alkyl)-piperazino, thiomorpholino or morpholino group.

By acyl residues R there are above all to be understood those of carboxylic acids. Possible residues are primarily the acyl residues of aliphatic carboxylic acids, especially of those having up to l 1 carbon atoms, such as of lower fatty acids, such as of lower alkanoic acids or lower alkenoic acids, for example propionic acid, butyric acid, trimethylacetic acid, acrylic acid, or valeric acid, IO-undecenoic acid, but above all acetic acid, or of substituted fatty acids such as halogen-fatty acids, such as halogen-lower alkanoic acids, for example monochloracetic or dichloracetic acid or trifluoracetic acid. Further possible acyl residues to be considered are the residues of aromatic or araliphatic carboxylic acids, such as of benzoic acids or phenylalkanoic acids or phenylalkenoic acids, for example phenylacetic acids, phenylpropionic acids, or cinnamic acids, and also the acyl residues of heterocyclic carboxylic acids, for example of pyridinecarboxylic, furanecarboxylic or thiophenecarboxylic acids. At the same time the aromatic or heterocyclic rings of these carboxylic acids can also be substituted, for example as specified below for the aromatic rings. Further, the acyl residues can be residues of carbamic acids or thiocarbamic acis, such Lower alkyl residues are for example methyl, ethyl, propyl or isopropyl residues or straight-chain or branched butyl, pentyl or hexyl residues bonded in any desired position. Lower alkoxy residues are above all methoxy, ethoxy, propoxy, isopropoxy or butoxy residues and possible lower alkenyloxy groups are above all allyloxy or methallyloxy residues. Fluorine, chlorine or bromine atoms should above all be mentioned as halogen atoms.

The new compounds possess valuable pharmacological, especially antimicrobial properties with a broad spectrum. Above all they possess bactericidal, bacteriostatic and especially fungicidal and fungistatic properties. Thus the new compounds are for example active against fungi such as for example dermatophytes, for example Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum gypseum, Epidermophyton floccosum and Keratinomyces ajelloi, as well as against aspergillus elegans and against the pathogenic yeast Candida albicans. Against dermatophytes, they for example already show a distinct inhibiting effect at a concentration of about 3 to 20 y/ml. The new compounds are therefore useful for the topical and systemic treatment of bacterial and especially of mycotic infections. The new compounds are however also valuable intermediate products for the manufacture of other useful substances, especially of pharmacologically active compounds.

Compounds to be particularly emphasised are those of the formula wherein R, denotes an optionally lower-alkylated cycloundecylidene, cyclotridecylindene or especially cyclododecylidene residue, R represents an optionally halogenated lower alkanoyl residue, for example an acetyl, monochloracetyl, dichloracetyl, or propionyl residue, a lower carbalkoxy residue, a benzoyl residue which is optionally substituted, for example as indicated, a carbamyl, thiocarbamyl, lower alkylcarbamyl or lower alkylthiocarbamyl residue or a phenylcarbamyl or phenylthiocarbamyl residue which is optionally substituted, for example as indicated, R and R each represents a lower alkyl residue, a lower cycloalkyl residue or a benzyl residue or R and R together with the nitrogen atom denote an optionally C-lower alkylated pyrrolidino, piperidino, morpholino, thiomorpholino, piperazino, N-lower alkylpiperazino or N-(hydroxylower alkyl)-piperazino residue, and alk represents the residue of the formula or especially the 1,3-propylene residue.

A particularly active compound is l-propionyloxy-l- (3-dimethylaminopropyl)-cyclododecane, which for example in the form of its hydrochloride, at a concentration of 3 to 6 y/ml, shows a distinct inhibiting action on dermatophytes.

Further compounds of importance are those of the formula wherein R R R and ]R have the indicated meanings.

The new compounds are obtained according to methods which are in themselves known.

The preferred procedure is to acylate a compound of the formula wherein R alk and R have the indicated meanings,

at the hydroxyl group.

The acylation takes place in the usual manner, for example by reaction with an anhydride or halide of an appropriate carboxylic acid.

An acid halide is above all the chlorine and as anhydrides there may be mentioned, in addition to the normal anhydride, for example, internal anhydrides, such as isocyanates, isothiocyanates or ketenes.

If R, is an esterified carboxyl group, a carbamyl group or a thiocarbamyl group, the acylation can also take place indirectly, for example by reacting with a dihalide of carbonic or thiocarbonic acid, such as phosgene or thiophosgene, and allowing the halogenated carboxyamino group thus obtained to react with an alcohol, a primary or secondary amine or with ammonia, or allowing the halogenated thiocarboxyamino group thus obtained to react with ammonia or a primary or secondary amine.

The reaction with the acid derivative takes place in the usual manner, preferably in the presence of an acidbinding reagent, such as an organic or inorganic base, for example pyridine or alkali carbonates or alkali acetates, preferably in the presence of a solvent and/or diluent, at lowered, normal or elevated temperature and in an open vessel or in a closed vessel under pressure.

Depending on the process conditions and starting substances, the final substances are obtained in the free form or in the form of their acid addition salts which are also comprised by the invention. Thus for example basic, neutral or mixed salts, and where appropriate also hemihydrates, monohydrates, sesquihydrates or polyhydrates thereof, can be obtained. The acid addition salts of the new compounds can be converted into the free compound in a manner which is in itself known, for example by means of basic reagents such as alkalis or ion exchangers. On the other hand, the resulting free bases can form salts with organic or inorganic acids. To manufacture acid addition salts, those acids which are suitable for the formation of therapeutically usable salts are especially employed. As such acids,

there may for example be mentioned: hydrohalic acids,

sulphuric acids, phosphoric acids, nitric acid, aliphatic, alicyclic, aromatic or heterocyclic carboxylic or sulphonic acids, such as formic, acetic, propionic, succinic, glycollic, lactic, malic, tartaric, citric, ascorbic, maleic, hydroxymaleic or pyruvic acid; phenylacetic, benzoic, p-aminobenzoic, anthranilic, phydroxybenzoic, salicyclic or p-aminosalicylic acid,

embonic acid, methanesulphonic, ethanesulphonic hydroxyethanesulphonic and ethylenesulphonic acid: halogenobenzenesulphonic, toluene-sulphonic and naphthalenesulphonic acid or sulphanilic acid; methionine, tryptophan, lysine or arginine, or cyclohexylsulfamic acid.

These or other salts of the new compounds, such as for example the picrates, can also serve for the purification of the resulting free bases, by converting thefree bases into salts, isolating these and again liberating the bases from the salts. Because of the close relationship between the new compounds in the free form and in the form of their salts, what has been said above and hereinafter with reference to the free compounds refers similarly also to the corresponding salts whenever such is possible or appropriate under the circumstances.

The new compounds can be in the form of optical an-' tipodes, racemates or isomer mixtures (racemate mixtures) depending on the choice of the starting substances (depending on the number of asymmetric carbon atoms) and on the methods of working.

Resulting isomer mixtures (racemate mixtures) can be resolved into the two stereoisomeric (diastereomeric) pure racemates in a known manner on the basis of the physicochemical differences of the constituents, for example by chromatography and/or by fractional crystallisation.

Resulting racemates can be resolved into the optical antipodes according to known methods, for example by recrystallisation from an optically active solent, with the aid of micro-organisms, or by reaction with an optically active acid which forms salts with the racemic compound and separation of the salts obtained in this manner, for example on the basis of their different solubilities into the diasteromers and the antipodes can be liberated from the diastereomers by the action of suitable reagents. Particularly usual optically active acids are for example the D- and L-forms of tartaric acid, di-o-toluyl-tartaric acid, malic acid, mandelic acid, camphorsulphonic acid or quinic acid. Advantageously, the more active of the two antipodes is isolated.

The invention also relates to those embodiments of the process according to which one starts from a compound obtainable as an intermediate product at any stage of the process and carries out the remaining process stages or in which a starting substance is formed under the reaction conditions or in which a reaction component is optionally present in the form of its salts.

Thus, in particular, the hydroxyl compound to be acylated can be employed in the form of its O-salts, such as the O-metal salts, for example the O-alkali metal salts such as sodium or potassium salts, or of the 0- magnesium halide salts, such as magnesium bromide salts, such as are for example produced in the Grignard reaction, that is to say the complex produced in the Grignard reaction can be directly reacted with the'acylating reagent.

Appropriately, such starting substances are used for carrying out the reactions according to the invention as lead ot the initially particularly mentioned groups of final substances and particularly to the specially described or emphasised final substances. r a

The starting substances are known or can, if they are new, be obtained according to methods which are in themselves known.

The compounds of the formula which are used as preferred starting substances can for example be obtained if a ketone of the formula wherein R, has the indicated meaning, is reacted with a compound of the formula Hal- Mg alk R wherein all: and R have the indicated meanings and Hal represents chlorine, bromine or iodine, and the resulting complex is decomposed.

The reaction of the compounds mentioned takes place in a manner which is in itself known, particularly in the presence of a solvent or diluent, for example, an ether, such as diethyl ether or tetrahydrofuran. The de' composition of the resulting complex is performed in the usual manner, for example by hydrolysis or aminolysis.

Resulting free compounds and salts can be converted into one another as described above and isomer mixtures which may be obtained can be resolved into the pure racemates, or racemates resolved into the optical antipodes, as described above.

The pharmaceutical preparations can for example be in the form of tablets, dragees, capsules, dusting powder, ointments. creams, powders, pastes or aerosols or in a liquid form as solutions (for example as an elixir or syrup), suspensions or emulsions. They are optionally sterilised and/or contain auxiliary substances such as preservatives, stabilisers, wetting agents or emulsifiers, solubilising agents, propellant gases and/or salts for regulating the osmotic pressure or buffers. They can also contain other therapeutically valuable substances. The pharmaceutical preparations for topical administration contain advantageously 0.25 to 5 percent, especially 0.5 to 2 percent of the active ingredient. The pharmaceutical preparations are formulated according to usual methods.

The compounds mentioned can also be employed in the form of feedstuffs or of additives for aninal fodder. Here the usual extenders and diluents and/or feedstuffs are for example employed.

The l-(aminoalkyl)-1-acyloxy-cycloalkanes and l- (aminoalkyl)-cycloalkanols described above can also be used as disinfectants or preservatives, for example for the disinfection of skin, of instruments; bandages, laundry or the like, and also for the disinfection and/or preservation of foodstuffs or fodders. They can be employed by themselves or mixed with the usual extenders or carriers. Y

The 1-(aminoalkyl)-1-acyloxy-cycloalkanes and 1- (aminoalkyl)-cycloalkanols described above also posses an insecticidal and acaricidal action as well as an action against phytopathogenic fungi and can be employed as insecticidal and acaricidal agents and also as agents against phytophathogenic fungi. Y

The agents according to the invention contain, in addition to the active substances described, a suitable carrier and/or other additives. Suitable carriers and additives may be solid or liquid and correspond to the substances which are usual in formulation technology such as for example natural or regenerated mineral substances, solvents, diluents, dispersing agents, emulsifiers, wetting agents, adhesives, thickeners, binders or Example 1 27.0 g (0.1 mol) of l-(3-dimethylaminopropyl)- cyclododecanol together with 200 ml of propionic acid anhydrice are'warmed for 5 hours to C in a bath. The mixture is concentrated by evaporation in vacuo, and the residue is taken up in 100 ml of ethyl acetate and mixed with 43 ml ofa 2.5 N solution of hydrochloric acid in ethanol. On adding a further 100 ml of ethyl acetate the l-propionyloxy- 1 S-dimethylaminopropyl)-cyclododecane hydrochloride of the formula 0 O--CHQ-CH;
